Integrating METAR Data into Wind Farm Operations

Since 1968, METAR is the most standard data format for networked micro-meteorological information. AUTO-METAR stations automatically generate METAR reports, especially from small airfields.

Advanced Wind Farm operations can apply METAR in real-time to anticipate sudden onset of events like frontal passage and downbursts. This may be especially useful for safe maintenance and repair of conventional HAWTs, as well as possibly essential for Airborne Wind Energy (AWE) operations that must “sense and avoid”, landing just in advance of extreme conditions, and relaunching just as soon as all-clear can be confirmed, for reliable maximum generation capacity.

Common METAR parsers today present graphical interfaces to technical users of many kinds, and also parse data for synoptic scientific meteorology, like tracking mesoscopic and planetary-scale atmospheric waves. In Wind Farm use, METAR parsing can help automate operational reasoning and action, like triggering Wind Farm emergency shut-down before damage can occur.
